HOLDING-TOOL FOR JEWELERS AND ENGRAVERS.

SPECIFICATION forming part of Letters Patent No. 327,558, dated October 6, 1885.

Application filed March 12, 1885.

To aZZ whom it may concern.-

Be it known that I, AUGUST KUDER, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Holding-Tools for Jewelers and Engravers and similar Artisans, of which the following is a specification.

My invention relates to an improved tool or clamp for holding jewelry and other similar small articles in an easy and convenient ptsition for engraving and polishing or finishing the same.

The nature of my invention will be fully explained by the following specification, and the drawings annexed, which form part of the same.

Referring to the drawings, Figure 1 is a side view of myimproved device. Fig. 2 is a longitudinal section of the same. Fig. 3 is a transverse section taken on the line :0 a" of Figs. 1 and 2.

In each of the views similar letters of referenceare employed to indicate corresponding parts wherever they occur in all the figures.

A and B represent a pair of levers, one of which, A, is provided with a semicircular transverse bearing, a, adapted to rest and vibrate upon a transverse bearing-piece, b, secured to the lever and provided at its upper surface with a curved surface adapted to fit freely in the semicircular transverse bearing a, formed in the under side of the lever A.

O is a pin which is passed through the levers A and B and the transverse bearing-pieces b, and with the bearing a and bearing-piece 12 forms a hinged connection between the levers A and B. The pin 0 is formed with a head, 0, which rests on the upper surface of the le ver A, while its shank 0 passes down a conical cavity, a, in the lever A, and is received piece I) and the lever B, and at its lower end it is riveted against a washer, E, applied on the under side of the lever B.

One end, F, of each lever A and B, I prefer to construct of a semi-globular or eggshaped form, while the opposite end, G, of the said levers A B is formed square.

The levers A and B externally I prefer to form round, or nearly round, but slightly tapering toward the end F; but this construction may be varied.

Serial No. 158,507. (No model.)

The levers A and B are held apart by the transverse bearing-piece Z1 sufficiently to allow of the said levers A and B being forced together when desired at either end by means of a wedge, H, applied as shown by Figs. 1 and 2.

The inner faces, 7c, of the levers A and B are formed flat, and at each end are provided with pads J, formed of leather or other suit able material, adapted to embrace the article to be treated, engraved or finished without damaging the same.

In the drawings I have shown a ring, K,

held in position in the end F by means of the levers A and B being forced at that end against the opposite sides of the ring K by means of the wedge H, which in this case is applied at the ends G between the levers A and B; but in cases where I desire to engrave, finish, or otherwise treat an article, the contour or other conditions of which require a flat or square-faced end, I should remove the wedge H from the end F, and hold the article to he treated by the ends G of the device, the wedge H being applied in this case between the surfaces of the ends F of the levers A and B.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. A tool for engravers and similarartisans, embodying in its construction a pair of levers provided at each end with pads or gripping surfaces adapted to be alternately or at will brought into position for operation by means of a wedge, substantially as shown and de scribed.

2. A tool for engravers and similar artisans, embodying in its construction a pair of gripping-levers pivoted on a transverse bar and held in position by a pin passing through the the same and a wedge for operating and. retaining the said levers firmly in a holding or gripping position, substantially as shown and described.

In witness whereof I have hereunto set my hand this 5th day of March, 1885.
